At the last West Coast Computer Faire the people from Emperical Research Group told me that they were running their 68K cpu at 10 MHz on the S-100 bus. Dual likewise has an S-100-based 68K Unix box running at 10 MHz. Dave Fylstra

This is an S-100 system with an 8 Mhz 8086 processor and math and I/O coprocessors. Also in discussions with Mark Garetz, chairman of the IEEE-696/S-100 standard commmittee, I have been given to understand that he has built prototype S-100 systems that have run at over 10Mhz using sample chips that I gather are not yet in production......Sol O ----- End of forwarded messages

From: Jerry E. Pournelle <POURNE@mit-mc> Compupro has -- in fact I have a copy of -- an 8086/8087 S-100 machine that runs at 8 mhz with the 8087 aboard and 10 if you don't use the 8087. (Obviously you need one of the superfast 8087 chips, not so easy to come by yet, from Intel.) One presumes that the S-100 bus is good up to about 10-12 mHz after which it probably begins to degrade. The last statement is a guess; I gathern tat Godbout's people are still t esting. Add that to the 10 mHz 68000 fylstra reports and you see the IEEE-696 isn't dead yet.
